Pausing a live teleconference call

ABSTRACT

Methods and products are described for facilitating a method of controlling participation in a teleconference call. One embodiment of the method includes connection to a teleconference call so that a user of a communications device is capable of participating in the call. Any real-time inbound audio and real-time outbound audio is recorded and stored. At some point during the call, a pause command is received that indicates a desire to suspend real-time participation in the teleconference call and that starts a pause process. One embodiment of the pause process includes continuing to record the real-time inbound audio but preventing it from being presented via the communications device until a resume request is received, preventing the real-time outbound audio from being sent to other call participants until a resume request is received, and enabling a resume option that allows the user to re-engage in real-time participation in the teleconference call.

Turning now to FIG. 1, a block diagram of an illustrative communications device according to one embodiment is provided and referenced generally by the numeral 100. Although some components are shown in the singular, they may be plural. For example, communications device 100 might include multiple processors or multiple radios, etc. As illustratively shown, communications device 100 includes a bus 110 that directly or indirectly couples various components together including memory 112, a processor 114, a presentation component 116, a radio 117 (if applicable), input/output ports 118, input/output components 120, and a power supply 122.

Power supply 122 includes items such as batteries, fuel cells, or any other component that can act as a power source to power communications device 100.

As previously mentioned, an embodiment of our technology facilitates a method of controlling participation in a teleconference call. Particularly, our technology enables a user to pause a live telephone call and also to fast-forward playback, rewind, and the like. By way of example, consider a situation in which a given user phones into a teleconference call that is composed of multiple other participants. During the course of a call, a situation arises in which the user would desire to temporarily postpone real-time interaction with the other participants while maintaining an ability to re-engage such participants at will. In this way, the user desires to pause the live telephone call.

In accordance with one embodiment of our technology, the user would indicate his/her desire to pause the telephone call, which would invoke a pause process that includes preventing any audio associated with the user from being conveyed to the participants but also records any audio information that is being conveyed by the participants. During this pause process, the user is free to listen to any previously recorded audio, fast-forward the audio, rewind the audio, etc. In some embodiments, a real-time transcription of the audio that is being communicated by the other participants is presented to the user, thereby enabling him/her to review any conversation that he/she missed during the pause process.

According to some embodiments of our technology, the system includes intelligent features. One illustrative intelligent feature includes an ability to monitor the audio information of the other participants for one or more key words. For example, a user might indicate a list of key words to be monitored for, such as his/her name, whether there are any questions, calls for meeting to end, etc. When one of the other participants mentions one of these key words, the system can indicate the same to a user and wait for another command or automatically carry out an action, such as jumping the user to live, and thereby enabling instant real-time participation with the other participants.

Turning now to FIG. 2, an illustrative operating environment suitable for practicing an embodiment of our technology is provided and referenced generally by the numeral 200. Operating environment 200 can include two or more communications devices that are coupled to each other to facilitate a teleconference call. By way of example, four communications devices are shown (210, 214, 216, and 218). As illustratively shown, communications device 210 includes a set of computer-executable instructions that are embodied on one or more computer-readable media of the computing device, which will be referred to herein as application 224. In one embodiment, application 224 carries out various functional aspects of the invention.

Each communications device is coupled to a network 212, which can actually be multiple networks such as one or more of the Internet, the PSTN, and other public or private networks. Network 212 is shown to symbolically represent a communications network(s) that enables a teleconference call to take place between the communications devices. As illustratively shown, the communications link 220 can be wire-line or wireless, as indicated by reference numeral 222.

One embodiment of our technology contemplates server side interaction by way of a server 226, which includes an application 228, which, in one embodiment, carries out functional aspects as described herein and can be done alone or in combination with application 224 as desired.

Turning now to FIG. 3, greater detail of aspects of a computing device is provided and referenced generally by the numeral 300. As illustratively shown, communications device 300 includes a speaker 310 and a microphone 312. Speaker 310 is usable to audibly present audio information that is received by communications device 300. Similarly, microphone 312 is usable to receive audio information and pass it through to a network such as network 212 such that other participants can hear what was said by a given user. Similar to application 224 of FIG. 2, application 314 is a set of embodied computer executable instructions that cooperate to carry out various functional aspects of the invention. In one embodiment, it is coupled to a controller 316 that processes information, and in one embodiment can be a processor of communications device 300. It is illustratively shown to be communicatively coupled to application 314 as well as microphone 312, a display 318, and can also access stored audio 317 when it becomes available.

Controller 316 is also illustratively shown by link 320 to be coupled to speaker 310. This does not mean that controller 316 needs to be connected to the speaker 310 per se; rather, it indicates that controller 316 has access to the same audio information that is often presented by way of speaker 310. As used herein, the term “audio information” is not necessarily distinct from “audio” per se. But in some embodiments it might include additional information such as touch tones of dialed digits, metadata, etc. As the participants participate in the teleconference call, the audio information generated by them is conveyed to communications device 300, and is accessible by controller 316.

Display 318 is usable to present textual information in embodiments that include a communications device that have such a display. Such textual information might include a transcription 322 of a piece of audio. It might include context 323 data that helps understand the context of a key word 324 a, 324 b that was stated. For example, one of the participants might ask “Do you know, John?” in a way that is asking whether John knows an answer to a given question. As will be explained, John 324 a might be a key word that triggers mobile device 300 to jump to live and rejoin the conference call. Including context information 323 to form a sentence 322 enables a user to get a sense of the context for the key word 324 a. In some embodiments, the invention does not jump immediately to live but presents an actionable control that, if acted on, would jump a user to live. For example, perhaps a box 326A is painted around the symbol such that if the box, acting as a button, is pressed then a user is placed into live participation in the teleconference call.

Other visual controls are also shown as being displayed, such as a progress bar 327, which includes an indicator 328 that indicates a level of progression of the conference call, and a portion 330 that indicates an amount of stored audio information. Other displayed controls (or optionally in the form of physical buttons) include a play button 332, a jump-to-live button 334, other buttons, as well as a pause button 336 that is usable to convey a desire to pause the teleconference call.

As will be described in greater detail below, communications device 300 is usable to join a teleconference call and also to pause, or temporarily postpone real-time participation in, the teleconference call. In one embodiment, communications device 300 works substantially independently to carry out aspects of the invention. In other embodiments, a server-side approach is utilized such that server-side components carry out some of the functions that will be described below as being carried out by communications device 300. In still other embodiments, communications device 300 works in more equal concert with a remote device (e.g., 226) to effect the invention.

Turning now to FIG. 4, an illustrative method for controlling real-time participation in a teleconference call is provided and referenced generally by numeral 410. It will also reference FIGS. 3 and 2 in connection with the steps of FIG. 4 to help explain an embodiment of our technology. At a step 412, a communications device is utilized to connect to a teleconference call. In one embodiment, a device such as communications device 300 is used to connect to a teleconference call. A user of device 300 can use device 300 to phone into the teleconference call. In other embodiments, an outside caller might call device 300 so that it is used to join the teleconference call.

At a step 414, the real-time inbound audio and real-time outbound audio that is communicated via the call is recorded. In one embodiment, this recording happens automatically. In another embodiment, a user can select an option to engage recording. The real-time inbound audio is audio that is spoken by other participants and communicated to the other participants; that is, to communications device 300. Similarly, the real-time outbound audio is that which is communicated from and through communications device 300. If a single user is using device 300, then his/her voice is communicated as real-time outbound audio. If communications device 300 is operating via speakerphone for example to host multiple users, then whatever audio is being communicated locally from and through device 300 is considered real-time outbound audio. In brief, whatever shared audio is communicated by way of the participants is recorded in one embodiment of our technology.

Another form of stored audio includes setup information that is received from a user. For example, when a user is initially prompted to say his/her name prior to joining a conference, that information can be recorded and stored (either locally or remotely). The system can then use this recording to carry out other aspects of the invention, such as monitoring for the person's key word. For example, if a user by the name of John calls into a teleconference call, is prompted to speak his name, utters “John,” then the system can receive this information and either use an audio footprint or textural transcription that enables the system to monitor for an occurrence of the word during the course of the teleconference call.

In one embodiment, stored audio 317 is locally stored on communications device 300. In other embodiments, the stored audio is stored on a remote device such as device 226.

At a step 416, a pause command is received, which indicates a desire to suspend real-time participation in a teleconference call and which begins a pause process. As previously mentioned, an embodiment of our technology allows a user to pause a live teleconference call. When the pause process is instantiated, such as by selecting button 336, then recording the current conversation continues but the user by way of device 300 is no longer engaged in real-time participation. For example, at a step 416 a, communications device 300 continues to record the real-time inbound audio but prevents it from being presented via the speaker 310 of communications device 300 until a resume request is received. In this way, real-time outbound audio is prevented from being communicated to the other call participants at a step 416 b. The pause process includes an ability to resume the call at will. Thus, at a step 416C, application 314 enables a resume option that allows the user of device 300 to rejoin the call. This can be activated by receiving the resume request, which, when received re-enables communication of real-time inbound and real-time outbound audio.

An exemplary use case could include a situation where a user of device 300 is engaged in a teleconference call but receives a high-priority call on a different device (such as a mobile phone, a different mobile phone, an office phone, etc.). The user does not want to end the teleconference call and also does not want to miss out on any of the conversation that will transpire while tending to the urgent matter. Thus, the user would engage the pause process (for example, by selecting button 336). Now, the user can deal with the urgent matter, which might include speaking near a proximity of microphone 312.

In one embodiment, such local audio that does not relate to the teleconference call is not recorded and stored as part of stored audio 317. After the user deals with the urgent matter, he or she might wish to review a conversation that has transpired since the call was placed on hold. In one embodiment, the audio from the teleconference call was prevented from being outputted via speaker 310. One way of reviewing the prior conversation is to listen to the recorded audio, which can be accomplished by way of selecting button 332 for example. In another embodiment, application 314 facilitated transcribing the conversation, and making it presentable by way of a portion 318 of the display of device 300. This would allow a user to quickly read as much as desired about the conversation that took place while the call was placed on hold. In still another embodiment, a user can select an option (not shown) to email a transcript or otherwise have the transcription sent to another device, such as a PC with a large monitor, so that viewing the transcription can be done even easier.

Although the user can re-engage in live participation in the teleconference call at will, application 314 can be set up so as to cause real-time participation to be automatically re-engaged in if a certain keyword is spoken. For example, either offline or in immediate advance of the call, a user can indicate a desired key phrase or set of key phrases that, if uttered, would result in communications device 300 acting in response to the utterance. One way of responding to the utterance is to immediately place the user of communications device 300 into real-time participation in the call. Another way of responding to such utterance might be to present a visual indication associated with the utterance.

As briefly alluded to above, the user might indicate a phrase such as “does anyone” as a key phrase. He or she might be concerned about not participating in a question that is posed to the group. If any participant utters the phrase “does anyone,” then application 314 could automatically place the user of device 300 back into real-time participation in the teleconference call. Two examples of transcriptions that show context are provided in FIG. 3 and referenced by the numerals 326A and 326B. Sample key phrases shown include “John” 324A and “Questions” 324B. In another embodiment, the user is jumped to a few seconds before real time, and those prior few seconds are played at an accelerated rate so that the user is able to understand at least some of the context in which the key phrase was uttered.

This type of presenting an indication that a key phrase was spoken is illustrated by reference numeral 418. In one embodiment, the indication is a visual indication. In another embodiment, the indication is an audible indication, and in still another embodiment, the indication is a feel indication such as a vibration action. Thus, the indications can be slight, along the lines of a blinking LED or lamp. Or the indication can be more aggressive such as causing the phone to vibrate or presenting a message on a display of device 300 or even presenting an audible tone, which can be system or user defined.

Turning now to FIG. 5, another method of controlling participation of a user in a teleconference call is provided, and referenced generally by the numeral 510. At a step 512, real-time participation is started in a teleconference call. A device such as communications device 300 is used to present real-time audio that is received from other participants and to communicate any real-time audio that is locally received from a user of communications device 300.

At a step 514, the real-time audio that is received from the call participants is stored. At a step 516, the outgoing audio from a user of device 300 is stored as well, collectively which make up stored audio 317 in one embodiment.

At a step 518, device 300 initiates a pause process in which the user's real-time participation in the teleconference call is paused but the connection to the call is maintained. The connection to the teleconference call is not severed when the pause process begins. Moreover, our invention is different than merely placing everyone on hold. Merely placing someone on hold does not afford an opportunity for the user to retrieve the audio information that was presented during the whole process and before the call was terminated. But our technology does allow for this. Hence, a playback option is enabled at a step 520. If a user acts on the playback option, then the stored audio is played back by way of communications device 300. A control such as slider 327 can be presented during playback of stored audio in one embodiment. The user is free to manipulate slider control 328 to navigate to any desired portion of the teleconference call. Moreover, because the audio continued to be recorded even while the call was paused, the user is enabled with an ability to listen to that portion of the conversation that was missed in addition to that portion of the conversation that has already occurred.

Turning now to FIG. 6, another embodiment of controlling participation in a teleconference call is provided and referenced generally by the numeral 610. This embodiment utilizes more server-side aspects than a more client-based solution. In this embodiment, a request is received from a given user as well as other participants to join a conference call at a step 612. In one embodiment, these requests can be serviced by server 226 and carried out by embodied instructions 228.

At a step 614, recording of all audio that is communicated via the call is facilitated. This can be accomplished by storing all of the audio at server 226 (or another storage device coupled to server 226). At a step 616, a request is received to pause the call. In one embodiment, this request is received from a communications device that is associated with a user. Thus, communications device such as communications device 210 communicates a signal to server 226 that a user of device 210 is going to enter into a paused state.

During this paused state, teleconference server 226 at step 618 continues to communicate audio information to the communications devices (including communications device 210) while preventing communications device 210 from being used to participate in real time in the conference call until a request to do so is received. During this time, any local audio that would have been communicated by way of communications device 210 is not communicated to the other participants 214, 216, and 218.

At some later point, a request is received to play back at least a portion of the recorded audio at a step 620 if desired. A user might not have any desire to review all of the audio. In such a case, the user can jump back to live to rejoin the call and then review the missed portion later, or contemporaneously by way of a written transcript. If the user does desire to review the missed portion, then server 226 receives a request to play back at least a portion of the recorded audio at a step 620. That portion is played back without dropping the user from the line at a step 622. In this way, a user of communications device 210 is able to hear what transpired in his or her absence (or at least a lack of real-time participation) and still have an ability to rejoin the call live.

At a step 624, server 226 receives a request to rejoin real-time participation in the call, which is facilitated at a step 626. Other technical aspects that were described in connection with the aforementioned local embodiment could be carried out by way of the server-centric embodiment as well. In the server-based environment, the audio is streamed in real time to communications device 210. In cases where communications device 210 is a mobile device, separate radios can be used. For example, the audio stream might be maintained by way of a voice connection, while the stored audio is communicated by way of a Wi-Fi connection or a 4G-radio connection for example.
